Cool game Raven! I find the mouse aiming engine really neat, and I glad you used it! It's just like playing Minecraft! Very good work for your first release of this game!

Unfortunately, I found after I shot a guy, the window faded, and a pop-up said that an unknown error had occurred, but then it disappeared, and 10 seconds later it happened again; just to let you know in-case you were wondering about bugs.

Usually the reason why the game does that is because since the PC that downloaded was not the host creator of that file, it'll usually glitch out untill ran twice.

Heck yeah! This is an awesome start to a game. I wasn't very good at it, but that's probably because I suck at computer fps'. I liked the sound effects and enemy poses. The scene at the very beginning was done very well. Keep up the good work!
